"When did you last..?" or "What was the last time...?"
I have some questions aobut these two begining question. I found in my English book this question "What did last ask me a question?" but found on Internet another similiar question "When was the last time you asked me a question?".
Are both correct?. But If the second one has a mistake, what's the misake and why's that?.
I hope you can help me about this issue.
